|Sources: Amazon, ManufacturerGarmin epix Pro (Gen 2) Sapphire Edition (47mm) vs Withings ScanWatch Nova
If you're torn between the Garmin epix Pro (Gen 2) Sapphire Edition (47mm) and Withings ScanWatch Nova, the Garmin is the standout option. It boasts a stunning 1.3" AMOLED display, compared to the ScanWatch's small 0.63" OLED, making it ideal for outdoor adventures and workouts. In real-world use, the Garmin's 16-day battery life is impressive, but the ScanWatch's 30 days might be a game-changer for those who want less frequent charging. The trade-off? You'll miss out on the Garmin's built-in GPS, which is essential for precise tracking during activities, while the ScanWatch relies on a smartphone connection for GPS features.
